GSE UK Conference 2007

"Virtually Yourz"

Abstract:

This top-rated session is one of a sequence of five which provide a quick and easy introduction to the most important elements of the IBM mainframe's Assembler Language. Each session covers key concepts to help you understand and write simple assembler programs, and provides illustrative examples. Your learning will be enhanced if you can bring a PC-compatible laptop; but if you can't, the lab sessions (8156 and 8157, 'Assembler 106A/Assembler 106B') will give you an opportunity to try out some sample programs. We will provide a diskette, CD, or flash drive with the ASSIST/I assembler and host emulator you can use to write, test, and print your programs. We will be available to help you at each session. Topics to be covered in Part 1 include: binary, hex, and decimal; number representations (1s complement, 2s complement, unsigned), and conversions among them basic hardware data types: binary, decimal, character (EBCDIC) main storage organization basic forms of binary arithmetic how to get started with ASSIST/I

After graduating from the University of Illinois (where I contracted an enduring computer virus), I worked at the Stanford Linear Accelerator Center, mainly in user support. I joined IBM in 1983, working initially on Fortran and inter-language issues, and in the early 1990s assumed responsibility for the High Level Assembler.
